Believe it or not, leptin wasn't discovered until 1994 and it pays a MAJOR role in our
health and ability to stay lean.
Leptin is a hormone made by your fat cells that is responsible for reducing hunger.
It is also known as your "satiety hormone," or "the master hormone of body fat regulation."
When you eat a meal, leptin gets released by your fat cells and travels to your brain.
It basically signals to your brain that your body is full and needs no more food.
It is an important hormone that aids in appetite control.
In obesity, there's a lot of body fat in fat cells.
Fat cells release leptin according to their size, so the more fat you have, the larger
the leptin levels.
Increased leptin levels from their full fat stores should be telling the brain to stop
the consumption of food.
The problem with obesity is that the leptin signal isn't working properly.
There's a ton of leptin floating around, but the brain is becoming unresponsive to the
signal, and is tricked into thinking there is too little leptin present.
Your brain has essentially become numb to the "stop eating" warning.
This condition is known as leptin resistance.
We've already talked about the hormone insulin and how we've become resistant to it…Well,
the hormone leptin is no different.
Leptin resistance develops in response to chronically elevated leptin levels, so the
brain eventually stops responding to the large amounts of leptin released, and you don't
get the signal to stop eating.
It mistakenly thinks the body is starving, even though it has more than enough fat stored.
First, our brain signals our body to eat more in order to not starve to death.
Second, it reduces our metabolism because the brain thinks we need to conserve energy,
making us burn fewer calories, and making us feel sluggish and lazy.
The good news, is you can reset your leptin sensitivity!
If you are overweight or obese, most likely you are leptin resistant.
This is the case especially if you have excess fat in the midsection.
A big key to preventing and reversing leptin resistance is following a diet that keeps
inflammation and triglycerides low.
There are several things that you can do right now to increase your leptin sensitivity.
They are to avoid processed food, consume healthy fats, exercise, sleep, reduce your
carbohydrate intake, and have a healthy protein intake.
Did you notice anything about these recommendations?
Yep these are the exact same guidelines for anyone just wanting to be healthy…Regardless
of their circumstance.
Eating whole foods, exercising and sleeping well are all lifestyle factors that contribute
to health and wellness for life.
Where does intermittent fasting come into play here?
Recent research in the International Journal of Obesity found that intermittent fasting
was effective at reducing leptin hormones and improving leptin resistance.
In addition, it fight inflammation and lowers triglycerides.
This is yet another reason to be a "sensitive" person!
